Emma Gonzalez, a student at Marjory Stoneman Douglas, directly addressed President Donald Trump and other lawmakers in her speech. “If the president wants to come up to me and tell me to my face that it was a terrible tragedy and how it should never have happened and maintain telling us how nothing is going to be done about it, I’m going to happily ask him how much money he received from the National Rifle Association,” Gonzalez said.

“We need to pay attention to the fact that this isn’t just a mental health issue,” Gonzalez added. “He wouldn’t have hurt that many students with a knife.”

And after every single shooting that’s what they say over and over again, but nothing ever changes,” Carly Novell, a 17-year-old student at the school, told TIME on Friday. “It has to be political because this happened because of guns, this happened because of the relaxed gun laws that we have.”

Vice President Mike Pence said during a speech Saturday that the Trump administration will make school safety a priority, but did not go into specifics, AP reports.
